This Lantern Fest sounds interesting to explore more. I learned that one will be held just outside Reno at the Fernley 95A Speedway
(1965 Highway 95A) on Saturday, October 17th. There are also others planned elsewhere in the US.
More information about the group is here:

ABOUT THE LANTERNFEST

At The Lantern Fest, thousands of revelers join together armed with lanterns for one unforgettable spectacle. There will be music, dancing, s’mores and, when the time is just right, we will light the sky with our highest hopes, deepest regrets, and fondest dreams.

These lanterns are 100% biodegradable. Not to mention after each release we have professional “Lantern Chasers” that will make those armored truck driving meteorologists look like your local news’ weatherman. These lantern experts collect 90% of the lanterns after the event.

Historically lanterns were used to symbolize good fortune, request favorable weather, or to celebrate the life of a loved one, just to name a few. But here in 2015, we don’t care if you are turning over a new leaf or just snapping some sweet shots for Instagram.

Families and friends can dance to the music, roast marshmallows, munch on snacks provided by local vendors, and of course, watch the lanterns float away in an unforgettable release.

Each registrant will receive their own lantern as well as some other goodies.
